I had a customer today saying that his email had been rejected as spam.
I'm not aware of any application that would reject an email at smtp time becuase it thought it was spam.
Certainly nothing that i've installed or ever seen in the last 6 years on Cpanel
I have a few RBL's but these reject on the basis that the sending IP/Domain is listed in an RBL, and not based on content.
I also have CSF mailscanner, but this would accept the message then quarantine or delete it, Mailscanner wouldn't send a rejection notice.
I can find no reference to this email in any of my exim logs.
I see no reference to my hostname or IP address in the reject headers.
I'm guessing that the bounce came from within the customers outlook environment, and nothing to do with anything at my end.
Could anyone help shed any light on where this reject notification came from, I'm not sure it came from me.
